Thank you! If we look at the assignment itself, we need to write down the code that defines parameters:
# Initialize parameters dictionary, by calling one of the functions you'd previously implemented
#(≈ 1 line of code)
# parameters = ...
### BEGIN SOLUTION
### END SOLUTION
If you plan to go on to the next course, I would suggest you to do their assignments on Coursera. If you really need to do them elsewhere, then perhaps you may want to just copy the solution codes back to your cousera notebook instead of uploading any notebook saved in Colab or other environment.
